20 Claims.

This invention relates to an apparatus for painting an identificationmark or band upon yarn holders, such as spools, bobbins and the likewhereby an identifying color can be imparted to the thread or yarn woundthereon. Manufacturers often require that certain yarns be placed onholders having a particular colored tip or other portion which isvisible after the yarn has been wound thereon. These colored tips serveto identify the position on a particular machine where the yarn is to beplaced or the use to which the bobbin or holder is to be applied. Oftencertain colored tipped holders are used in association with certain yarnnumbers to prevent mixing of different numbered yarn or cotton.

There are other uses to which this identifying color matr beplaced whichare well known in textile circles.

It is an object of this invention to provide an apparatus for quicklyand efficiently markingl these holders with a suitable colored material,such as paint. The disclosed embodiment of the invention is particularlyadapted for painting the tips of bobbins. This apparatus has meanswhereby a paint saturated brush is moved in contact with the bobbin, andthe bob-bin is simultaneously rotated so that the paint will be appliedto the bobbin tip. After the tip has been painted the brush is withdrawnand a measured quantity of paint is automatically applied thereto forthe next operation. l

It is another object of this invention to provide an apparatus of theclass described, in which a brush is used for applying paint to a bobbinor other type of yarn holder, in combination with means for changing theposition ofthe brush relative to the holder surface which it contacts sothat a different portion of the brush will contact the holder at eachoperation. This apparatus serves to prolong the life of the brush aswell as to insure that a more uniform painting or marking job will beproduced. If only one side of the brush contacted the holders orbobbins, then after several bobbins had been painted, the brush wouldbecome set and the fluid or marking solution would not flow from thebrush to the holder uniformly, and the paint would collect on the sideof the brush which did not contact the yarn holder.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds, when taken in connection withthe accompanying drawings, in which- Figure lis a plan view of theinvention;

Figure 2 is an elevation looking at the near side of Figure 1;

Figure 3 is anl elevation looking at the right hand side of Figure 1;

Figure 4 is a plan view similar to Figure 1, but showing the markingmeans in contacting relation with the yarn holder;

Figure 5 is an enlarged vertical sectional view taken along the line 5-5in Figure 1 Figure 6 is a sectional view taken along line 6-6 in Figure5;

Figure 7 is an isometric view of the bracket embodying a stationary camfor operating the paint feeding means and also the dog which actuatesthe brush reversing means;

Figure 8 is a detail view taken along line 8-8 in Figure 4, showing thebrush in contacting relation With a bobbin tip. l

Referring more specifically to the drawings, the numeral I0 denotes asuitable table which is mounted upon upright legs I I. A bolster l2penetrates and is secured to the table Il), by any suitable means suchas a nut Ill. The upper end of the bolster has a spindle I7 rotatablymounted therein to which a whorl I6 is secured, said spindle beingusually integral with the whorl. The spindle Il serves to removably holda suitable yarn holder such as a bobbin I8 theraround.

In Figure 2, the yarn holder I8 is shown in dotted line raised positionand also in dottedpline lowered position. The raised position is theposition that it occupies when first inserted upon the spindle; whereasthe lowered position is the position that it occupies when it isrotating to receive paint or other marking fluid on certain portionsthereof. The bobbin ris not shown in Figure l, but in Figure 4 thebobbin is shown in bold lines in contacting position with the brush orpaint applying means. Mounted on the whorl I6 is a belt 20, which beltis also mounted upon a pulley 2| on motor shaft 22, said motor shaftextending upwardly from electric motor 23. The motor is placed intooperation when it is desired to rotate the bobbin for painting purposes.The bobbin of course is rotated by virtue of frictional contact with therotating spindle Il; however, there is a loose fit between the bobbinand the spindle which allows a limited amount :of slippage, resulting inthe bobbin rotating at a slower speed than the spindle. y

rl`he table I0 has mounted therein a vertically disposed shaft 26. Thelower end of the shaft 26 is adjustably secured to the table member bymeans of nuts 2l and 28 threadably secured to the shaft above and belowthe table member l0.

By manipulating the nuts 21 and 28, the shaft 26 and its associatedparts can be adjusted vertically to accommodate different lengths ofbobbins.

The shaft 2S also has a collar 38 xedly mounted thereon by means of setscrew 3|. This collar serves as a base for supporting a sleeve 32 whichsleeve is mounted around the shaft 26 for oscillating movement.

A bracket 34 is secured around the upper end of the sleeve 32 by meansof set screws 35, said bracket being adapted to support a platform 3Bupon which a container 31 is mounted. The container has a projection 38extending from one side thereof which penetrates a hole 39 in springextension 40, said extension forming an integral partI of the platform36. The projection 38 can be snapped in and out of the hole 33 when itis desired to insert or remove the container 31 from the platform.Figure shows the method of attaching the platform 36 to the upperportion of bracket 34 and it is here seen that a suitable screw 38a isemployed for this purpose.

Leading from the lower portion of the container 31 is a pipe or nipple45, said nipple having a restricted opening 46 therein leading into thecontainer, which opening communicates with an enlarged opening 41(Figure 5). The restricted opening 45 is normally closed by a ball 4Bwhich ball is pressed into position by means of a spring 49 within thebore 41. The bore 41 communicates with another small opening 58, saidopening leading to a vertically disposed bore 5| in a cylinder 52. Theopening 5U is small enough to prevent the escape of the spring 49therethrough, but at the same time large enough to permit paint 53 orother marking fluid within the container 31 to pass therethrough.

Cylinder 52 is supported by an annular member 54 secured to a lug 55a onthe container 31 by means of a screw 54h.

Mounted in the bore 5| is a piston 55 which is secured to the lower endof a stem 55. This stem penetrates a cap 51 on the upper portion of thecylinder 52 and has mounted on its upper end an enlarged knob 58 whichserves to confine a compression spring 59 around the intermediateportion of stem 56 and above the cap 51. Knob 58 is adapted to contact astationary cam surface B0, at times, to cause the piston 55 to be moveddownwardly to expel fluid from the bore 5| through an opening 65. Theopening 55 is similar to the opening 50, just described. The outer endof opening 55, that is the end farthest removed from the bore 5| isnormally closed by a ball 56, which ball is disposed in an enlargedopening 61. It will be noted that cap 51 is threadably secured on theupper end of cylinder 52. By turning this cap, the elevation of the nutcan be varied thereby varying the depth that piston 55 can penetratebore 5|. The depth of penetration of the piston determines the amount ofpaint drawn into and discharged from bore 5|. A spring B8 is disposedinthe bore 61 for normally pressing the ball 66 over the opening 65.This spring is normally held in position by means of a dispensing member68, said dispensing member being threadably secured in a projection 61a,in which the bore 61 is placed. The dispensing member S9 has arestricted opening therein, to permit the marking fluid to escapetherethrough, and this dispensing member isof such a shape that thelower end thereof is disposed in close proximity to a brush 12. Thebrush 12 is mounted in an extension 13, said extension extendinghorizontally from shaft 14.

Shaft 14 is rotatably mounted in bracket 34 and has a pinion 15 fixedlysecured thereon, which pinion meshes with a larger pinion 16. Pinion 13is rotatably mounted on shaft 11 which is secured in bracket 34.Integral with the pinion 15 is a ratchet 18 and this ratchet is adaptedto be engaged by pawl 83 (see Figures 3 and 6), when the parts are inthe position shown in Figure 3. The pawl 8|] is pivotally secured as at8| to bracket 83 which bracket has integral with the upper end thereofthe cam portion Ell previously described and also has integral therewitha laterally extending arm 84, which is secured to the extreme upper endof the vertically disposed shaft 23 by any suitable means such as setscrew 85. The pin 86 is provided in the lower portion of member 83, saidpin being adapted to penetrate the vertically disposed leg of the pawl8D. A compression spring 81 is disposed around pin 86 which normallyrotates the pawl 8U in a counterclockwise manner and also causes thelower end of the pawl to normally engage the teeth in the ratchet 13. Itis seen that the pawl and its associated bracket 83 remains instationary position at all times; whereas the container 31, cylinder 52,dispensing means 69 and brush 12 rotate about the shaft26. In otherWords, the normal position of the parts is as shown in Figure 1, atwhich time the brush 12 is removed from the spindle I1 and the bobbinI8; whereas in Figure 4, the brush is shown in an engaging position withthe bobbin |8. When the parts move from the position shown in Figure 4back to normal position as shownin Figure 1, the lower end of the pawl8|lis engaged by the teeth in the ratchet members 18 thereby causing theratchet member to rotate a predetermined amount. This turning of theratchet 18 will cause the `pinions 15 and 15 to turn and also will causethe brush 12 to rotate through an angle of degrees to thereby presentthe opposite side of the brush 12 to the bobbin upon the next paintingoperation. By referring to Figures 3 and 5, it is seen that the iiatside of brush 12 is normally disposed at a slight angle to the vertical,so that one side thereof will be in position to receive the paint orother marking material dispensed from member 69. When the brush isrotated to contacting position as shown in Figure 4, the brush isrotated slightly by this Contact until the flat side is substantiallyvertical. This last named rotation is permitted since the dog 8B isdisengaged at this time, and also since there is a slight clearancebetween the lower end of dog 88 and the teeth of ratchet 13 (Figure 6).

In order to insure that the ratchet 18 remains in the position to whichthe pawl 8U has rotated it, a slack pawl 88 has been secured as at 89 tothe .bracket 34. The lower end of this pawl normally engages the teethin the ratchet wheel 18 by virtue of its weight and thereby preventsreverse rotation of this ratchet at all times. There are times, however,when the brush 12 must be secured against forward rotation, such as whenthe dog 80 is not engaging the ratchet wheel 13. This forward rotationis prevented by providing a leaf spring 14a (Figures 5 and 6) which issecured to bracket 34 and has its free end frictionally engaging shaft14, to which brush 12 is attached.

The bracket 34, container 31, dispensing member 68 and brush 12, arenormally held in the position shown in Figure l' by means of a suitabletorsion springgSD, said spring having one end thereofsecured'tothecollar 3| and its other end secured to a lever 9i, which lever is inturn secured to the sleeve 32A by any suitable means such as set screw92. Lever 9| as will be seen by referring to Figures 1 and 4, has a slot93 therein which is penetrated by an upstanding pin 94, said pin havingits lower end secured to a lever 95, which lever is mounted on shaft 95said shaft being pivotally secured in a bracket Bl. The free yend of thelever 95 is adapted to rotate in close proximity to the spindle l1. Whenthe free end is in raised position as shown in Figure 2, a bobbin I8 isinserted on the spindle and the free end supports the lower end of thebobbin. When the bobbin is pressed downwardly from the uppermost dottedline position to the lowermost dotted line position (Figure 2), theinterior of the bobbin is engaged by the rotating spindle Il androtation is imparted thereto. At the same time, the upstanding pin 94rotates the lever 9|, sleeve 32, container 31, dispensing member 69,brush 12 and ratchet 18 in a clockwise manner from the position shown inFigure l to the position shown in Figure 4, thereby causing one face ofthe brush 'l2 to be placed into contact with the upper tip end of thebobbin i3 for painta colored band i8 thereon (see Figure 8). Upon therelease of lever 95, by the operators hand, the bobbin is moved fromlowermost dotted line position to the uppermost dotted line position andat the same time, the brush, container and the associated partsare movedback from the position shown in Figure 4 to the position shown inFigure 1. Upon this reverse movement, the pawl 80 will engage theratchet T8 and thereby cause the brush l2 to be reversed. At the sametime, the projection or enlarged portion 58 on the upper end of the stem5S will engage the stationary cam surface SB to thereby cause thecylinder 55 to be moved downwardly and to expel a measured quantity ofmarking material from the cylinder through the dispensing member 69 andonto the brush 12. It is seen yby referring to the construction shown inFigure 5 that when the piston 55 is moved upwardly by Virtue of thespring 59 that a charge of paint is drawn into the bore 5| and when thecylinder is moved downwardly, this same charge is expelled from thisbore.

As heretofore stated, the bobbin I8 is placed upon the spindle H withthe base thereof resting upon the free end of lever 95. The operatorshand is simultaneously engaging the lever 15 and the bobbin I8 and inthis position the bobbin is pushed downwardly from upper dotted lineposition in Figure 2 to lower dotted line position until the base of thebobbin I8 frictionally contacts the spindle. The operators hand is thenreleased from the bobbin I8 and at the same time, the lever 95 ispressed still farther downwardly out of contact with the base of thebobbin as shown in dotted line position in Figure 2. During the rotationof the bobbin, the operators hand holds the free end of the lever 95 outof contact with the base of the bobbin and after the painting operation,the lever is released by the operators hand which in turn will raise thebobbin to upper dotted line position in Figure 2, by virtue of the forceexerted by torsion spring 9G and thus rotation of the bobbin will cease.

The downward movement of the free end' of lever 95 is limited by a stop|00. The stop is of a suitable height so as to retard the downwardmovement immediately after the bobbin has frictionally engaged thespindle l1.

In the drawings and specication there has been set forth a preferredembodiment of the invention, and although specific terms have beenemployed, they are used in a generic and descriptive sense only and notfor purposes of limitation, the scope of the invention being set forthin the appended claims.
